How we Spray

Ground Sprayers Common in production

Agriculture

How we Spray Aerial Spraying

Good for Wet soil conditions Bad for hip pocket

How we Spray Specialty Application

Turf Vegetable, Fruit Spot Spray

GPS

Increase accuracy Lower cost on fuel, chemical, and other Input cost Precision pays

May not pay for its self but it helps Most GPS Can be use in more than one, so

don’t figure the cost on just one Implement

AIM Command PWM (pulse width modulation) Select and control, All independent

Pressure Rate Speed

Normal system, One is dependent on the other two Pressure+Rate=speed Speed+Rate=pressure Speed+Pressure=Rate

Nozzle, pump and other components may play a roll

Aim Command "On-the-go drift control" by toggling preset pressures

controlled independently of field speed and product rates.

Improved field operations More management control of field operations

Limits off-target application risk Limits opportunities for operator error

More time applying with increased average field speeds and fewer tip changes Gained from improving low speed efficiencies and from

stretching high speed limitations 3 to 24 mph speed range at a constant pressure Greater range of GPA rates from a single tip

Swath Control Pro

Automatically turns sections of spray boom on/off with the use of bounders and GPS

http://stellarsupport.deere.com/en_US/support/sprayerVideo/

Helps Minimize Overlap or Minimize skips Helps cut on chemical cost, and waste

Put it All Together

Aim Command + Swath Control Plus+ GPS Auto Track = You sitting there, oh and you have to turn, but

there working on that.
